Title: Mangeto-optical recording element
Inventor: TAKAHASHI AKIRA
IPC: G11B11/105
Filed: 1989-06-12
Abstract: PURPOSE:To enhance Kerr rotation and incident light quantity and to obtain high S/N by providing a transparent thin film comprising silicon nitride having larger refractive index than that of a transparent substrate, and a magnetic thin film on a substrate. CONSTITUTION:A transparent thin film 2 comprising silicon nitride, and a magnetic thin film 3 having an axis easy of magnetization perpendicular to the film surface are provided on a transparent substrate 1. A reflecting film and a heat insulating film are provided between the film 3 and an adhesive layer 4. The refractive index of the film 2 is made larger than that of the substrate 1. The incident light through the substrate interferes in the film 2 to enhance the Kerr rotation. Since silicon nitride of the film 2 has high thermal conductivity, heat can be propageted from the silicon nitride even when larger quantity of incident light is given. Consequently, the quantity of reflected light can be enhanced. By this method, high S/N can be obtained with large Kerr rotation and high intensity of incident light.

Title: Position aligning method of semiconductor substrate
Inventor: YAMADA YOSHIAKI
IPC: G03F9/00
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To enable detecting a mark covered with a metal film, by grasping the change of a reflected laser beam as the waveform of a thermal wave signal, and applying the peak position to an alignment mark position. SOLUTION: A recessed mark 41 a for position alignment which is formed of a silicon oxide film 21 is filled with an Al alloy film 22, and the surface is completely flattened. On the surface, a photoresist film 23 is formed. A silicon substrate 20 in this the state is step-scanned in the arrow direction by an XY stage. In each step, a thermal wave signal, i.e., intensity of a reflected light is measured. In the part where the silicon oxide film 21 is not present under the Al alloy film 22, it is directly connected with the silicon substrate 20. As a result, thermal conductivity is high, and it is not necessary that independent patters in X and Y are prepared as in the case of thermal wave. The spatial resolution of an image obtained in this direction is determined by the step pitch.  When an alignment mark can not optically detected, alignment is enabled with equivalent position precision.

IPC: C12M3/00
Filed: 1990-06-07
Abstract: PURPOSE:To enable safe continuation of gas concentration control in a culture chamber by controlling the gas concentration in the culture chamber with a specific controller, simultaneously sensing the residual state of a main gas supply source and performing control with a reserve flow controlling means. CONSTITUTION:A control output is produced by a controller 17 constructed from a microcomputer to average the oxygen gas concentration in a culture chamber 2 and control the concentration to the set value (SV). A variation (e) of the oxygen gas concentration inputted from an electric conductivity sensing type sensor 16 is periodically [e.g. 1 min interval (S1) to (Sn)] and successively calculated with the controller 17 during opening of a valve 10. If the residual amount of nitrogen (for oxygen control) in a main gas cylinder 7 is small, the variation (e) is reduced. If the gas cylinder is emptied, the variation (e) turns to increase. If the variation (e) is smaller than the prescribed value, an alarm means 18 is operated with the controller 17 to raise an alarm. A main valve 10 is simultaneously closed to open a reserve valve 14. Thereby, the gas concentration control can be stably continued and damage to cultures can be surely prevented.

Abstract: PROBLEM TO BE SOLVED: To allow positive and negative polarities to be displayed so that they can be easily recognized visually without lowering resolution by displaying on a bar graph from different zero value points with displayed directions of positive polarity and negative polarity reversed. SOLUTION: When positive data is to be displayed on bar graph display 10, a left end of the display 10 is a zero value point 11 and a right end is a positive full scale value point 14, in which a bar graph extends from left to right as a positive data value increases. When negative data is to be displayed, the right end of the display 10 is a zero value point 16 and the left end is a negative full scale value point 17, in which the bar graph extends from right to left as a negative data value increases. In addition, a color for display may be changed when the data is of positive polarity from when it is of negative polarity to have the polarity of the bar graph display recognized. Therefore, positive and negative polarities can be visually recognized only with the bar graph display, while resolution is not lowered.
